Answer:
8. the length is 88/5cm or 17.6cm
Step-by-step explanation:
8.perimeter =2L + 2W
when you convert the width 42/5 = 8.4
so 52 = 2L + 2*8.4
52= 2L + 16.8
52 - 16.8 = 2L
35.2 = 2L
divide both sides by 2
L = 17.6cm
Answer:
a)b=4
b)x=-9
c)r=6
Step-by-step explanation:
Question 2.
a)5b+6=26
5b=26-6
5b=20
b=4
b)6-x=15
-x=15-6
-x=9
x=-9
c)r/2+2=5
r/2=5-2
r/2=3
Multiply both sides by 2 to remain with r
r/2×2=3×2
r=6.

Answer:
264 inches
Step-by-step explanation:
Let's start with the top cube.
We can figure out the volume by multiplying the length, width, and height. So for this problem, it will be 4x5x6. 4x5 is obviously 20, and 6x20 is 120. So the top cube is 120 in.
The bottom cube has the dimensions 4x6x6. I know 6x6 is 36. So 36x4 is 144.
So 120+144=264
